SOLAR SYSTEM

Detailed explanation-1: -The air in Earth’s atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen. Air also has small amounts of other gases, too, such as carbon dioxide, neon, and hydrogen.

Detailed explanation-2: -Oxygen is a major component of the solid earth, along with Si and elements such as Mg, Ca and Na. Nitrogen is not stable as a part of a crystal lattice, so it is not incorporated into the solid Earth. This is one reason why nitrogen is so enriched in the atmosphere relative to oxygen.

Detailed explanation-3: -’ Nitrogen makes up 78 per cent of the air we breathe, and it’s thought that most of it was initially trapped in the chunks of primordial rubble that formed the Earth. When they smashed together, they coalesced and their nitrogen content has been seeping out along the molten cracks in the planet’s crust ever since.

Detailed explanation-4: -The composition of the current atmosphere is 78% nitrogen, 21% oxygen, 1% argon with only 0.03% carbon dioxide. These proportions are for clean dry air; the water content in air can vary greatly from nearly none in the driest deserts to about 4% in the tropics.

Detailed explanation-5: -In fact, nitrogen is the most abundant element in Earth’s atmosphere: approximately 78% of the atmosphere is nitrogen! Nitrogen is important to all living things, including us.

Detailed explanation-6: -According to education site Vision Learning (opens in new tab) Earth’s atmosphere is composed of approximately 78 percent nitrogen, 21 percent oxygen, 0.93 percent Argon, 0.04 percent carbon dioxide as well as trace amounts of neon, helium, methane, krypton, ozone and hydrogen, as well as water vapor.
